The Effect of Using Montmorillonite on Reducing Radon in Soil

Exposure, takes place every day from natural and artificial sources, but the highest dose is related to normal radiation, which most of it is related to radon exposure. According to the World Health Organization reports, radon after smoking is considered as the second leading cause of lung cancer in the community (Salgado, 2015) (Wheeler, 2012). Ramsar is known as the riskiest place in the world in natural gas radon exposure. Given that, many people in their life or work, such as researchers, miners, hospitals, government offices, schools are exposed to the radioactive material, the feasibility of using available and affordable materials as an adsorbent of radon gas can play an important role in increasing public health (Yousefi, 2014). The objective aim of this study is investigating of various factors affecting radon reduction with montmorillonite in areas with high natural radiation. Effects of weight, adsorbent particle size, humidity, comparison of different materials to reduce radon were considered as other aims of this research.
